Description Alexander Köplinger 2016-03-02 20:27:40 UTC
Something broke on Linux with TLS recently, e.g. with the snapshot build from 2016-02-26+23.40.37:

Heard that it's "working fine in c9e1f8 and then breaking in 051f49".
Comment 2 Dylan Borg 2016-03-12 11:06:20 UTC
I am experiencing something similar and have been stuck running f0b9f524fa81b043ac57a9c6ebc6e8d231a0f1e9 instead of the latest code which is still broken to this day.
Comment 3 Alexander Köplinger 2016-03-15 02:19:28 UTC
I bisected this down to https://github.com/mono/mono/commit/80741c16fdd267534cbe33c188c581dcc92c0c69, should be fixed with https://github.com/mono/mono/pull/2762.
Comment 5 Alexander Köplinger 2016-03-16 02:49:11 UTC
I tried with the latest snapshot build and it works fine now. Thank you for the quick fix Martin!
